Push Start Key Fob (Prox Key) Programming for Monroe, Washtenaw, and Lenawee Counties & Surrounding SE Michigan Areas.
A push start key fob, also known as a proximity (prox) key fob, is a modern car key that allows you to start your vehicle without inserting a traditional key. Instead, it uses radio frequency identification (RFID) technology to communicate with your car when the fob is nearby—usually within a few feet. When the fob is detected inside the vehicle, you can start the engine by pressing a button, making it a convenient and secure alternative to traditional keys.
We can program new prox keys for most makes and models on the road today!
Push-to-Start (Prox) Key Fob Programming & Emergency Blade Cutting
At CS Lock and Key, we specialize in programming and cutting Push-to-Start (also known as Proximity or Prox) key fobs for most vehicles on the road today. Whether you’ve lost your key fob, need a spare, or your current one isn’t working properly, we’ve got you covered.
Our expert technicians can program new key fobs to work seamlessly with your vehicle’s push-button start system. In addition to programming, we also cut the emergency key blade housed inside the fob—essential for unlocking your car doors manually in case the battery dies or electronics fail.
As a family-owned, veteran-run business, we take pride in delivering fast, reliable service with integrity. Let us help you get back on the road with confidence.
Why it's important to make sure you have a spare
Don’t get stuck without a spare push start (prox) key fob—losing your only working fob can leave you stranded and facing high replacement costs. Many dealerships charge $400 to $700 or more for a new prox key fob, not including towing fees if your vehicle can’t be driven. Having a spare fob on hand saves you time, stress, and money in the long run.
At CS Lock and Key, we offer a more affordable, convenient alternative to the dealership. We can program and cut spare prox key fobs for most makes and models—often at a fraction of the dealer's price.
